Temperature & Humidity
Environmental Chamber Controller
Accurate programming of temperature and humidity is provided by
the advanced X26 controller. 50 customer named programs can be
stored with up to 100 steps per program and 500 steps in total.
Boost heat, boost cool and compressor On/Off outputs are included
as standard.
Two user programmable event outputs are available to activate
external devices - such as vibration test equipment.
A real time clock can be set to start a program at defined times of
the day and week.
Program profiles can be set up either through the controller front
panel from iTools or via a Windows setpoint program editor. This
allows the storage of an unlimited number of programs and easy
editing and transfer of programs between controllers. iTools
software will save and reproduce, the complete configuration of the
controller. iTools also provides trend plotting facilities for
monitoring the process.
The advance features include program holdback, to guarantee soak
time at temperature and humidity and six sets of PID parameters to
give accurate control under varying combinations of temperature
and humidity.
The humidity can be derived from wet and dry bulb inputs or taken
directly from a humidity probe.
Modbus digital communications is available for connection to
supervisory computers or Programmable Logic Controllers.

iTools Software
iTools is an advanced sofware tool for configuring the X26 and setting up the setpoint programs. The iTools configurator will edit,
store and ‘clone’ complete controller configurations. iTools employs an OPC to Modbus server to communicate with the X26. The
OPC server can be used as a link to other client software packages such as Labview and Wonderware.
Setpoint Program Editor
The setpoint program editor is a simple
way of setting up the humidity and
temperature profiles and the
programmable event outputs. The
editor will store, retrieve and download
program profiles. It will work ‘on-line’,
when program values are edited ‘live’ in
a connected controller, or ‘off-line,
when programs are edited before being
downloaded to a selected controller.
The number of stored programs is
limited only by the capacity of the PC
hard disk.
OPC scope is an iTools utility providing
trend plots of the process variables.
The time axis can be adjusted between
1 minute and 1 month. Data can also
be logged to hard disk in CSV format.
This can then be recalled and analysed
in an Excel spreadsheet.
